Description
As a certified reference material (CRM), 2,3,5,6-Tetrafluorophenyl isothiocyanate meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
CATO supplies 2,3,5,6-Tetrafluorophenyl isothiocyanate (CAS 207981-49-5), a certified reference material (molecular formula C7HF4NS, MW 207.15 g/mol) for analytical method development and quality control.
2,3,5,6-Tetrafluorophenyl isothiocyanate (C7HF4NS) contains a nitrile group, sulfur-containing functionality, fluorine substitution, an aromatic ring system. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
